AI-Powered supplier vetting
SummaryThe supplier is identified as a factory in Minhang District, Shanghai, operating in manufacturing. It reports nearly 20 years of attention to quality and safety management, holds ISO9001, ISO14001, ISO45001, CNAS 17034 and national second-level standard substance qualifications, and has exported since 2019, with exports representing 21%–30% of total sales. Its stated capabilities include gas supply across multiple product types, technical support, gas application guidance, research and innovation in several specialized gas fields, more than 10 production lines, and 11–20 quality-control staff. Evidence is insufficient to assess overseas service infrastructure, OEM/ODM, 3D design, customer cases, financial credibility, or several sustainability and digital capabilities.
Supplier typeThe supplier is explicitly identified as a factory, located in Shanghai's Minhang District, with manufacturing listed as the industry of associated companies. This supports classification as a manufacturing supplier.
CertificationsThe supplier states that it holds ISO9001 quality, ISO14001 environmental, ISO45001 occupational health and safety, and CNAS 17034 certifications, and is a national second-level standard substance unit. ISO9001:2015 and ISO14001:2015 are also separately listed, providing explicit evidence of multiple management-system qualifications.
After-Sales capabilityThe supplier explicitly states that it provides satisfactory after-sales service, relevant technical support, and gas application guidance, with cooperation forms adapted to different customer gas requirements. This is direct evidence of an offered after-sales and technical-support capability, although no service performance metrics are provided.
R&D capabilityThe supplier reports long-term research and innovation in gas-related fields including VOCs, electric light sources, halogenated hydrocarbons, chips, semiconductors, and electronic gases. It also states an intention to increase research investment and pursue industry-university-research cooperation; nine years of total R&D engineer experience is listed, supporting an innovation capability assessment.
Production capacityThe supplier states that its capacity distribution and product diversity support safe, stable, and complete gas supply. It operates more than 10 production lines and has 11–20 quality-control staff, which explicitly supports substantial production and quality-management capacity.
Customization capabilityThe supplier states that it can adopt different cooperation forms according to customers' diverse gas requirements and provide technical guidance. However, OEM, ODM, 3D design, and related product-development customization capabilities are marked unknown, so the broader customization scope cannot be fully verified.
